4IMZEROYIEMEWJJ IN COFFEE-MILLS.

The Schedule referred toiintheselLettex-s Patent and making part of the same u To all whom it may concern;

Be it known that I, FnAxois CHARLES RICHER, ot' Gilmer, in the county ot Upshr and v State of lexas, have invented a new and improved Coffee- Mill; and I ydo hereby declare that the following is` a I'nll, 'cleznyand exact description thereof, which will enablev others skilled in the art tomake and use the saune, reference being had to the accompanying drawing forming part of this spe'cih'cat-ion.

My invention' relates', to upright coffee-mills, and consists `in an'improved construction thereof, whereby the bearings are always maintained in their true relative position, while'the strain on the two is nlade automatically connteracting, and each part of the shell firmly and eicctually supported by the other.

. Figure 1 is a Vertical section, and' Figure 2 a plan view of a. codec-mill.

A is a rotary grinder.

B, a shaft which rotates it?, and

c, the crank to which power is'applied.

C C' are the two parts which form'the shell.

It will be perceived, from iig. l of drawing, that C has three sides, bbb, and that, on each ot' the two opposite of these a. rightangled recess, j; is formed.

The part C is also composed of three sides, c and'd d, but has each of the latter provided with a shoulder, g. l y l The model of operation is as follows:

' 'lhe part O of the shell being made fast to a bracket, or any suitable support, and located' inan upright postion,:the projecting shouldersg` g are tted snugly into the recesses' f of `the part C. y

The operator, in turning the crank c, bri-ugs a down cost nearly as much as a. new coffee-mill.

Witlf the construction shown the'part C of the shell, upon which the downward pressure is brought, rests securely upon C, which receives the upward pressure. l

' Under these circumstances the two parts of ,the shell are not held merely by the attaching-pins or screws, but are made to counteract and counterbalance the opposite tendencies of each other.' One, therefore, cannot move without its companion, and the mill will continueto grind uniformly until worn out Having thusdescribed all that is necessary to a lclear understanding' of my invention,

Vhat I esteem to be new, and desire to protect by Letters Patent, is-

In an upright coffee-mill, a. shell formed of two parts, C b f and: C c d, applied together, as and for the purpose specified. A
